EDIVARD CRANE, OF DORCHESTER, MASSACHUSETTS.

LOCOMOTIVE-ENGINE.

To all 'whom 'it may concern:

Be it known that I, EDWARD CRANE, of Dorchester, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Passenger-Locomotives; and I hereby declare that the following is a true and exact description thereof.

My improvement consists in combining a boiler, engine, water tank, coal box, blower and baggage department on one long truck frame suspended underneath the axles or journals bringing the weight of all near the rail as herein described.

The drawings hereto annexed as a part of the specifications being referred to for the purpose of rendering the description more intelligible and the letters referring to the different parts to designate the same.

I provide 2 parallel sticks of timber 4() feet long 2 feet deep 5 inches thick a, connected together by cross ties of the same dimensions at each end and immediately following the flange wheels and in rear of the drivers and 2 cross pieces in connection withthe flat wheels to which the blower is attached b, and 2 inside wheel pieces c, being framed into the cross ties directly under the axles of the drivers forming the water tank d, the whole being covered underneath with iron or wood excepting the openings for the wheels and brakes. The boiler, e, is then placed directly behind the drivers and let into the frame a, to the depth of about one foot and securely bolted to the side pieces a, and cross pieces Z), an iron frame is constructed about 14 feet in length 6 inches wide, 1% inches deep framed together at the ends-by cross ties of the same dimensions upon which the bed plate f, of the cylinders is let in and securely fastened upon this bed plate f, are placed two oscillating cylinders g, about 12 inches in diameter and of 24 inches stroke with a governor and cut off operated in the same manner as stationary engines, the pedestals for holding the boxes are connected and securely fastened and then the whole frame is securely fastened to the lower frame by bolts. The driving wheels, L, about 6 feet in diameter without flanges with outside bearin s are then placed in their position in the pe estals and connected by an outside connection, a yoke, z', is then passed over the pedestal and box, j, and suspended to the frame by bolts and springs, la, adjusted in such a manner as to equalize the weight upon the drivers at each end of the frame are placed two guide wheels, Z, with flanges about 24 inches in diameter with inside bearings so arranged as to allow a lateral movement of about 3 inches in the frame carrying the weight underneath the journals with a spring placed in the frame on a line with the center of the axles with suliicient strength to draw the frame in a line with the guiding wheels. The steam will be taken from the steam chamber and conducted by a pipe m passing down at the end of the boiler to the top of the water tank, then passing directly to the cylinders underneath the axles, this pipe will be incased in a pipe or box, which pipe or box will conduct the exhaust steam to the smoke pipe thereby keeping the steam pipe warm and protected. The exhaust steam can be used for heating the water in the tank or for any other useful purpose as it will not be wanted for the purpose of draft.

The engineer will occupy a seat directly over the axle of the hind pair of drivers with a steam and water gage directly behind him. The fireman will occupy a vacant space directly in the rear of the boiler having charge of the blower, water pumps and firing 2 stationary pumps are placed directly over the fire doors of the boiler and made fast to the boiler' and operated by steam at the pleasure of the fireman. A blower is. arranged by placing a pulley upon the axle of the wheels immediately following the boiler connected by a belt with another pulley in the baggage room in such a manner that the fireman can when in motion regulate the speed at pleasure. There are two loose cranks placed in the baggage room for the purpose of operating the blower when at rest if desired.

Ihe vacant space formed between the 2 hindermost axles may be used as a water tank the whole being inclosed with a covering of doors and windows of sufficient width to allow of a passageway on each side the boiler from the forward to the rear end of the engine the doors covering the front made in 4 parts of suflicient height to admit of the drivers being rolled out without disturbing the covering, the panels of the doors should be made of plate glass so as not to obstruct the view of the engineer--about 15 feet of the rear end of the engine may be partitioned o and used as a baggage or second class car. y

The brakeman will occupy a platform directly in front of the cylinders who will operate the brakes by two wheels in the ordinary form with one of Cramers spring brakes attached to each or by the use of steam as may be thought best so that the brakes may be set throughout the entire train simultaneously, one of the wheels will move the brakes throughout the entire train so as to bear upon the wheels by the rotary movement of a rod l inches in diameter passing through the under part of the entire train connected with a universal joint so as to allow the cars to stand atrdiferent angles and still preserve a rotary movement the other rod operating in the same manner bringing 6 or more shoes directly in contact with the rail by which means the brakeman has control of the train to an extent not heretofore attained.

The smoke pipe is placed on the outside of the roof horizontally at such height that it may enter a light pipe placed upon the top of the connecting car or cars' so as 'to form a continuous pipe theY Whole length of the train for the purpose of carrying the cinders smoke and exhaust steam to the rear of the whole train, the connection of the pipes between the cars may be made of fine wire gauze covered by an india rubber sack the ends confined by rubber elastics in such manner as to be readily connected and disconnected, a damper being placed on the top of the chimney so aS to be opened and closed at the pleasure of the reman so that in backing the train or standing still the smoke may pass immediately out of the chimney.

I claim- The combination in a locomotive, of a boiler, and engine with a water tank, coal boX, blower and baggage department on one long truck frame suspended underneath the axles of the wheels arranged substantially as herein described.

EDWARD CRANE. Attest:
